In vivo exogenous antigens typically cannot
induce cytotoxic T lymphocytes (CTLs), a key player in antiviral defense. A
recent study sought to see whether HLA-A*0201-restricted hepatitis C virus (HCV)
peptides could be delivered via a non-live prototype vaccine based on
immunopotentiating reconstituted influenza virosomes. The pathway was
successful, as CTLs were primed and the target cells infected with recombinant
vaccinia virus encoding the HCV core protein were specifically lysed. The
peptide is protected from numerous degrading viruses when the virosomes are
delivered in vitro.
